Autumn recently arrived according to the calendar. A few days later weather here cooled and it felt like Autumn. I was able to wear jeans and was starting to break out the blankets and long sleeves. And then this week happened.

Back to temperatures in the 90+ degree range. My mood was thrown into a place of unhappiness and discontent. This is unusual for me so naturally I wanted to know why I was so affected by that change in weather.

It turns out our brains use our circadian rhythms and the length of day to synchronize with the seasons. So basically the length of available daylight is still becoming shorter, but the temperature was in alignment with what we expect with shorter days. Our circadian rhythms are driven by exposure to light.

So my rhythm is responding to the change in daylight and I am expecting cooler temperatures to go with this. I will continue to get myself and my home ready for the cooler weather because I know soon it will come and stay.
